This invention relates to a cleaning rod, and is partcularly concerned with a rod for cleaning the barrel of a shotgun, rie or pistol.

When a gun barrel is cleaned it is customary to coat its interior with oil to protect it. A cleaning rod constructed in accordance with the present invention comprises a rigid rod and a plurality of soft cloth patches held firmly at their centers in longitudinally spaced relationship relative to said rod. The cloth patches are preferably of some soft fibrous material, and may be made of either natural or synthetic fibers. The cloth patches may be made of any suitable synthetic material. The cloth patches are held firmly at their centers on both surfaces of the cloth to permit them to be pulled or pushed through a narrow opening, such as a gun barrel, without displacing any of them. The cloth patches apply a thin coating of oil to the inside of the gun barrel as they are being pulled out of the barrel.

The cleaning rod of the present invention is provided with an adapter for holding one or more circular patches of softcloth which can be inserted into the gun barrel in one direction, and reversed without withdrawing the rod so that the entire cleaning and oiling operation may be performed by pushing the rod through the barrel in one direction and then pulling it out in the opposite direction. Preferably the rod is inserted into the muzzle end of the gun barrel and pushed until the patches enter Y the breech. Y

A standard size rod may-be used with adapters of different sizes for either a shotgun, rifle or pistol of any size bore, although it may be preferred to use a larger rod for shotgun's than for rifles `or pistols.

The diameter of the adapter to be used depends upon the bore of the gun barrel to be cleaned, but it is possible to use the same adapter with barrels of slightly different bores. The number of patches secured to the rod also varies with the bore of the barrel. It is preferred to use three patches for shotgun barrels, and a single patch for rifle or pistol barrels.

Flexible spacers in the form of grommets made of material not soluble in oil are used in conjunction with the patches. The diameter of the grommets used is preferably slightly larger than the diameter of the widest portion of the adapter and slightly smaller than the bore of the gun barrel to be cleaned. The grommets are provided with circumferential Vgrooves which act as reservoirs for small quantities of oil. The oil is applied lightly to the patches before the rod is pushed into the gun barrel.

-When the rod is pushed into the gun barrel the patches are compressed, and some of the oil squeezed from the patches ows into the circumferential grooves. Qn the return stroke of the rod, the oil flows from the clrcumferential grooves to the patches, and the patches apply it as a light coating to the inner surface of the gun barrel.

The structure by means of which the above and other advantages are attained will be described detall m the Afollowing specification, taken in conjunction with the d '2,862,218 Fatented Dec. 2, 1958 ice embodiment of the invention, n which:

Fig. 7 is a detail perspective view of one of the spacing grommets.

In the drawings, the reference numeral 2 indicates a rod having an axial threaded bore 3 in one end. An adapter 4 comprises a threaded pin 5 projecting from one side of a cylindrical disk 6 and a threaded pin 7 projecting from the opposite side of the disk. Pins 5 and 7 are aligned axially, and are both integral with the disk 6. Pin 7 is pointed, for reasons hereinafter disclosed, and has a diameter different from the diameter of pin 5 to insure proper assembly of the adapter and rod without difliculty. The diameter of pin 5 permits it to fit in the threaded bore 3, and the'diameter of pin 7 permits an internally threaded cap 3 to be threaded thereon.

The diameter of disk 6 is dimensioued inaccordance with. the bore of the gun barrel to becleaned, being smaller thanvsaid bore, The cap Sis providedwi'th an integral flange 9 adjacent its open end. The diameter of f lange9 is Vsubstantially the same as that of'disk'. The

closed end of cap 8 is knurled lon its outer cylindricaladapter betweendisk 6 and ange 9 of capV 8.v AThe patches are preferably'peforated through the center'prior to their assembly with the adapter. The pointed end 11 also facilitates impalement of grommets 15 and threading of cap 8 on the adapter.

The spacing grommets 15 are preferably made of Neoprene, but may be made of any flexible fibrous material that is not soluble in oil. The grommets are apertured to tit on the pin 7 and are preferably slightly Ylarger in diameter than the diameter of disk 6 and ange 9. Each grommet is provided with a circumferential groove 16 which acts as a reservoir for small quantities of oil during a portion of the cleaning operation, as hereinafter described. If desired, the grommet may be provided with two circumferential grooves instead of the single groove shown in the drawings.

It is very simple to assemble the grommets 15 and patches 12, 13 and 14 with the adapter 4, and to assemble adapter 4 with rod 2. A patch 12 is impaled on pin 7 and pushed into juxtaposition with disk 6. Then a Vgrommet 15 is impaled on the pin and pushed into contact with one face of patch 12. If additional patches are to be used, patches 13 and 14, and grommets 15 are impaled on pin 6 in the same order, and cap 8 is tlghtened against the last patch 14. The adapter, with the patches` n 3 and grommets `secured in place, isgthen assembled with the rod merely by threading pin 5 in bore 3.

The method of cleaning and oiling the gun barrel with thelitodI hereindescribed, isy very `simple-sA The ,ii-rse; step in the cleaning operationis-theVassemblyi-of.an.-adapiter; ofpropersizenwith: the rod..` .Ar-small quantity of` oil; is then fapplied to the tiexiblegcloth,patches- .12,13-a17rd 14.

. During.v thistirstmovementof. the .patches from;-the muzzle ofthe gunha'rrel, to the bree;ch,.- the patch V14V closest to cap l8 sbstantially covers the other two patches and` picks. up allthe dirt removed from Ythe innersurface of thegun barrel' 17'. The patches are compressedsomewhat during this movement so that some-of the-oillap plied: to the patches is squeezedrout of them int'o the thelgun barrel inthe reverse direction. The reverse fold-` ing, of the patches .positions the patch 12 closest to the dislrA 6wonv the outer side, and the patch 14, which carries all the dirt removed from the barrel on the irst' movement, on the inside. Accordingly, patch 12, which engages the inner surface of the gun barrel on the return movement of the cleaning rod, is clean and will not r'elease any dirt tofall 'back into the barrel. The patches are also compressed upon the return movement, thereby causing them to deposit a light coating of oil on the inner surface of the gun barrel 17 as the cleaning rod is withdrawn from the barrel.

If only a single patch is used, that patch will have one surface exposed to the barrel to pick up the dirt from the barrel: as it is being pushed through the barrel, and the other surface exposed on the withdrawal of the cleaning rod, when the light coating of oil is deposited on the inner surface of the gun barrel. When a single patch is used it is preferred to use a grommet on each side of. the patch.

The cleaning rod mayalso be used to polish the insideof' a gun barrel by applying any suitable polishing material, such as, for example, jewelers rouge, totheV cloth patches, and then running the rod throughthel dry gun barrel.
